TRANSMISSION OF LOCATION INFORMATION OF A MOBILE STATION IN A GPRS/INTERNET ENVIRONMENT

摘要

A telecommunication network comprising a roaming mobile station(MS) coupled to its Home IP Network (HIPN) via a mobile network MN, apacket-based wireless communication network (GPRS), preferably operatingaccording to the "General Packet Radio Service" [GPRS], and anINTERNET. The status and the location of the mobile station MS is indicated bylocation information or signaling, as the "Routing Area Updates" [RAU] to theGPRS network and the "Registration Request" messages (RR) to the Home IPnetwork (HIPN), generated by a location signaling circuit (LS) of the mobilestation. In order to optimize the transmission of signaling over the radiolink(RL) of the mobile network (MN), i.e. to limit as much as possible the loadthereon, only the Routing Area Updates are transmitted over the radio link.The Registration Request messages are derived from the Routing AreaUpdates in the GPRS network and so further transmitted to the Home IPNetwork (HIPN).
